This problem could be fixed at times through targeted furnace repairs.
What is a Heat Exchanger?
In any structure of natural Gas Furnace, a Heat Exchanger is a very significant part of this appliance where the furnace basically heats the air. It is a metal Clam-shaped Chamber, where heat from the gas combustion chamber transfers into the air coming from the blowing fan, ultimately moving into the system’s ventilation. At any time, the combustion gas never comes into contact directly with the air. If this dare happens, the living spaces will be filled up with unhealthy fumes. The heat emitted by the combustion gas increases the Heat Exchanger’s temperature, air from the blower passes through it and heat gets transferred into it.
What is the Problem of Having a Cracked Heat Exchanger?
This is because exhaust fumes that include carbon monoxide from the heat exchanger could seep into the air through the cracks that normally develop on the metal. Carbon monoxide is considered among the most toxic gases, which is responsible for severe health problems in human.
Cracks in heat exchangers are mostly caused by corrosion. This weakening of the heat exchanger metal is created by a gradual reaction between the combustion gas and the metal. This is the reason as to why you need to be keen on old furnaces. You should not even ignore the smallest crack, as they will ultimately widen as the heat exchanger expands whenever it turns hot.
A cracked heat exchanger is well identified by watching out for a clicking sound produced by the furnace when the blower shuts off. If you are having trouble with your furnace or heat exchanger it is best to call one of the experts at Emergency Maintenance company to repair the problem
